LAKE COUNTY -- The FBI is seeking the public's assistance in identifying alleged victims of convicted killer Curtis Dean Anderson, which includes a victim he claimed to have picked up in Clearlake in late 1984.

Anderson, who died while serving his prison term on Dec. 9, 2007, was convicted and sentenced to more than 300 years in prison for the 1999 kidnapping and murder of 7-year-old Xiana Fairchild in Vallejo and other crimes, according to an FBI press release published Monday.

He was captured after one of his kidnap victims, then 9-year-old Midsi Sanchez, was able to escape.

Anderson was interviewed by FBI agents in November 2007, and he confessed to murdering eight victims in the United States, which includes Fairchild, according to the release.

His second victim was a young female hitchhiker in her late teens, whom Anderson claimed he picked up on a road near the northeast side of Clearlake a few days after the death of his first, according to the report.

Anderson described the first victim as a female in her late teens/early 20s. He allegedly met and killed her and disposed of her body near a swimming hole in Marysville. She was a "runaway," according to Anderson.

The remaining six victims he described were killed between early 1985 and December 1999, with Fairchild being Anderson's last.

Anyone with information regarding the identity of the alleged victims should call the FBI San Francisco tip line at 1-800-CALL-FBI (1-800-225-5324). All calls are confidential and tips can be left anonymously.
